2 Claims. (Cl. 299-20) This invention relates to an improved liquiddisinfectant dispenser for toilet flush tanks.

The primary object of the invention is to provide a simple, efficient,and inexpensive device of the character indicated which can be quicklyand easily installed in and removed from a toilet flush tank, and whichdispenses disinfectant directly to the body of water in the tank.

Other important objects and advantageous features of the invention willbe apparent from the following description and the accompanyingdrawings, wherein, for purposes of illustration only, a specificembodiment of the invention is set forth in detail.

In the drawings:

Figure 1 is a fragmentary perspective view of a flush tank showing adisinfectant dispenser in place therein, in accordance with the presentinvention;

Figure 2 is a side view of the dispenser showing the cap in placethereon and the dispenser in a condition to be stored or transported;

Figure 3 is an end view of Figure 2;

Figure 4 is a vertical transverse sectional view through the dispensertaken substantially on the line 4--4 of Figure 2, and showing the capremoved and the wick extended to discharge liquid disinfectant into thewater of a toilet flush tank.

Referring to the drawings in detail, a toilet flush tank designatedgenerally which is open at the top and has removably supported thereon aconventional cover 14, and a back wall 16 which is spaced from the frontwall 12 which carries a conventional control lever 18 by means of whichthe flush tank valve is opened to discharge the water from the tank. Thesubject matter so far described is conventional and forms no part ofthis invention except in combination therewith. The illustrateddisinfectant dispenser is designated generally 20 and comprises anelongated generally flat container 22 having a top wall 24 having anopening 26 surrounded by an upwardly extending screw threaded nipple 28.Fixed in the back wall 21 of the container 22 adjacent the upper endthereof, and under normal circumstances extending downwardly from thetop of the container in spaced parallel relation are tongues 30, which,as illustrated in broken lines in Figure 3 and in full lines in Figure4, are adapted to be bent upwardly to provide a horizontal arm 32 anddownwardly to provide a vertical arm 34 to define hooks which engageover the upper edge of the back wall 16 of the flush tank 10 to suspendthe container 22 in. the flush tank against the back wall 16 and abovethe level 35 of the body of water in the tank when the tank is full. Intransportation and storage of the dispenser 20 a screw threaded cap 36is threadably engaged over the nipple 28, but during use the cap 36 isunscrewed from the nipple, as illustrated in Figure 4, and depends intothe body of water in the flush tank 10. Secured to and extending axiallythrough the open end of the cap 36 is a rod 38 having a loop 40 on itsfree end embracing one end of e 2,770,492 C Patented Nov. 13, 1956 awick 42 which extends through the nipple and the tending stop bar 44which, when the cap 36 has attained a predetermined distance below thebottom of the container 22, engages the under side of the top 24 of thecontainer to arrest downward movement of the wick. The stop bar 44 ispositioned a distance from the free end 41 of the wick 42 sufficient toenable the free end 41 of the wick to reach the bottom 43 of thecontainer 22 so that all of the liquid contained within the containercan be siphoned out by the wick and dispensed with the water in flushtank 10, it being understood that the siphoning action is achieved byreason of the capillary action exerted in the wick 42 for the liquid Lcontained in the container 22.

In use, the container 22 may be transported with the tongues 30 lyingadjacent the back wall thereof, as illustrated in full lines in Figure3, so as to occupy but a minimum amount of space. When it is desired touse the contents of the container 22, the tongues 30 are bent, asillustrated at 32 and 34, into hooks for engaging over the upper edge ofthe back wall 16 of the flush tank 10 to suspend the container in placethereon. The cap 36 is then unscrewed and the part of the Wick betweenthe cap and the stop bar 44 is withdrawn from the container.

While in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that minor changesin the details of construction, combination and arrangement of parts maybe resorted to without departing from the spirit and scope of theinvention as claimed.

What is claimed is:
